Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise Embodiment, broadly falls into the scope of protection of the invention.
The embodiment of the present invention provides a kind of wireless communications method, for Long Term Evolution (Long Term Evolution, LTE), senior Long Term Evolution (Long Term Evolution Advanced, LTE-A), 3-G (Generation Three mobile communication system) (3rd- Generation, 3G) and worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, WiMAX) etc. in wireless communication system, base station side can support Full-duplex wireless communications, and UE side can not be supported entirely The radio communication carried out under the scene of duplex wireless communications.Wherein base station can carry out radio communication according to the steps, stream Journey figure is as it is shown in figure 1, include:
Step 101, is grouped the subscriber equipment in the service area of base station.
Subscriber equipment, when for user equipment allocation resource in its service area, can be first grouped, base by base station Stand and can be grouped according to preset strategy, such as the ability of the interference that other equipment produce carried out point according to subscriber equipment Group, assigns to same group by the subscriber equipment producing interference performance bigger, thus reduces the interference between subscriber equipment as far as possible; Or subscriber equipment is carried out random packet etc..The most preset strategy can be that user is the most preset in a base station, its Concrete content does not cause limitation of the invention.
During concrete implementation, subscriber equipment can be grouped by base station by following several ways:
(1) the path loss information of subscriber equipment in base station can obtain base station service area, and by path loss difference less than preset The subscriber equipment of path loss scope assign to same packet.Here path loss information refers to that wireless signal is between the two communication devices Loss in transmitting procedure, in the present embodiment, path loss information can be used to the disturbed condition weighing between subscriber equipment, road Damaging the interference between close subscriber equipment relatively big, subscriber equipment close for path loss is assigned in same packet by base station.Specifically Ground, base station can obtain UE by the signal intensity of the signal intensity of the upward signal of measurement UE or measurement UE feedack Path loss information.In the present embodiment, the upward signal of UE includes detecting reference information (Sounding Reference Signal, SRS) signal etc., UE feedack includes Reference Signal Received Power (Reference Signal Received Power, RSRP) etc..
In other embodiments, base station can also be by obtaining the interference feelings that other parameter determines between subscriber equipment Condition, and according to disturbed condition to subscriber equipment be grouped after so that the interference of the subscriber equipment between different grouping is less.
(2) service parameter of subscriber equipment in base station can obtain base station service area, and just service parameter is consistent Same packet assigned to by subscriber equipment, and described service parameter includes portfolio and/or type of service.Owing to different user devices has Different business demands, so by subscriber equipment inconsistent for service parameter is assigned to different grouping so that base station is for each During the user equipment allocation resource of individual packet, the resource that user equipment allocation that service parameter can be given different is different, it is contemplated that The business diversity of subscriber equipment.
Such as: base station can be the more downlink radio resource of the user device configuration in the packet that downlink traffic is big, for The more ascending wireless resource of user device configuration in the packet that upstream traffic is big, for the packet that up-downgoing portfolio is the least In the more idled radio resource of user device configuration, for the user device configuration in the packet that up-downgoing traffic fluctuations is big relatively Big flexible Radio Resource.
(3) multiplexing (Duplexing) technology that in base station can obtain base station service area, subscriber equipment is supported and/or Multiple access accesses (multiple access, MA) technology, and will support identical multiplex technique and/or the user of multiple access technique Equipment assigns to same packet.Wherein multiplex technique include FDD (frequency division duplex, FDD) and Time division duplex (time division duplex, TDD);And multiple access technique includes orthogonal frequency-time multiple access (Orthogonal Frequency DivisionMultiple Access, OFDMA) and single-carrier frequency division multiple access (Single Carrier-Frequency Division Multiple Access, SC-FDMA) etc..
It is appreciated that subscriber equipment can also be grouped by base station in other way, such as subscriber equipment is entered Row random packet, this mode is simple, wherein considers that some subscriber equipment is the UE of legacy version (legacy) or initial Access the UE of this base station, then base station cannot obtain the information such as disturbance state of these UE, and the UE of legacy version processes the energy of interference Power is more weak, and such base station can be by legacy version and/or be initially accessed the subscriber equipment of this base station and assign in same packet;And base Stand in when being grouped, the information such as the number of subscriber equipment in each packet, or the total quantity of packet can be limited.Wherein old edition This UE refers to not support the subscriber equipment of full duplex standard.
Step 102, the user device configuration Radio Resource pattern being grouped for each, specifically can include in following resource At least one: time-domain resource uses pattern (the use pattern of such as subframe), and frequency domain resource uses pattern (such as frequency domain money The use pattern of source block), time-frequency domain resources uses pattern, and code domain resource uses pattern and spatial domain resource to use pattern etc., its In, the Radio Resource pattern for the user device configuration in same packet is identical, for user device configuration between different grouping Radio Resource pattern is different.
Being appreciated that in a wireless communication system, Radio Resource, according to service condition, can be divided into ascending wireless resource, Downlink radio resource, idled radio resource and flexible Radio Resource.Wherein uplink and downlink Radio Resource is necessary.And it is wireless Resource is different according to attribute, mainly includes time domain, frequency domain, code domain and spatial domain resource.And Radio Resource pattern is when referring to base station pair The configuration pattern of territory, frequency domain, code domain and/or spatial domain resource, or perhaps UE is to time domain, frequency domain, code domain and/or spatial domain resource Using pattern, i.e. specify which Radio Resource is used as ascending wireless resource, which Radio Resource is used as downlink radio resource, which Radio Resource is used as idled radio resource, and which Radio Resource is used as flexible Radio Resource.Wherein, idled radio resource refers to base Standing or UE neither receives data on this Radio Resource and the most do not sends data, flexible Radio Resource refers to that base station or UE are wireless at this In resource unfettered, data can be received, it is also possible to send data.
Step 103, according to the Radio Resource pattern of configuration, selects to be respectively at different communication shape in same wireless resource Multiple subscriber equipmenies (at least two subscriber equipment) of state communicate, and communications status includes uplink state and descending here Reception state.
Base station is after being configured with Radio Resource pattern, when communicating with subscriber equipment, can first carry out up-downgoing and join Right, and carry out the radio communication of full duplex with the subscriber equipment matched.Wherein up-downgoing pairing refers to select same wireless resource On be respectively at multiple subscriber equipmenies of different communication state;And on same Radio Resource, some subscriber equipment is come Say, can be only in a kind of communications status, be i.e. in uplink state or be in downlink receiving state.Carry out up-downgoing pairing In multiple subscriber equipmenies, on identical Radio Resource, some subscriber equipment carries out uplink, and other subscriber equipmenies are carried out Downlink reception.So base station is on some Radio Resource, can receive some or certain user while downlink data sending The upstream data of equipment.
When after the user device configuration Radio Resource pattern that each is grouped by base station, due to the UE use in same packet Radio Resource pattern is identical, it is impossible to carries out the UE between up-downgoing pairing, only different grouping on some Radio Resource, just can divide Different communications status does not occur, up-downgoing pairing can be carried out.Such as, packet 1 configuration ascending-descending subframes configuration 0 is given in base station, Giving packet 2 configuration ascending-descending subframes configuration 2, wherein in the subframe that subframe numbers is 3,4,8 and 9, the UE in packet 1 is in up Transmission state, the UE in packet 2 is in downlink receiving state, then base station can be right in the subframe that subframe numbers is 3,4,8 and 9 The UE of packet 1 and packet 2 carries out up-downgoing pairing.
If it should be noted that the UE being initially accessed and/or legacy version UE is assigned to same packet by base station, it is contemplated that base Standing factors such as cannot accurately knowing in this packet the disturbed condition of subscriber equipment, base station can not be to the UE of this packet and other points The UE of group does up-downgoing pairing, and i.e. base station is in same wireless resource, does not select the subscriber equipment of this packet, and with this packet The subscriber equipment of other packet that subscriber equipment has different communication state communicates, and specifically, base station will not be in some nothing Both receive the upstream data of this grouping user equipment in line resource, send again the subscriber equipment that downlink data is grouped to other.
Further, in the present embodiment, after base station is configured with Radio Resource pattern, can by high-level signaling or under Row controls the signaling of channel bearing and notifies the Radio Resource pattern of configuration to corresponding subscriber equipment.Wherein, descending control is believed The signaling of road carrying belongs to physical layer signaling;For high-level signaling (High Layer Signaling) is relative physical layer signaling , it is from the slower signaling of higher level and transmission frequency, wireless heterogeneous networks (RRC, Radio Resource can be included Control) signaling and medium education (MAC, Media Access Control) signaling etc..Preferably, base station is by specially RRC (dedicated RRC) signaling the Radio Resource pattern of each subscriber equipment is notified each subscriber equipment respectively.
Visible, in embodiments of the present invention, in the system of Full-duplex wireless communications is supported in base station, base station needs to take it Subscriber equipment in the range of business is grouped, and is the Radio Resource pattern that the user device configuration of same packet is identical, for not With the Radio Resource pattern that the user device configuration of packet is different, so in base station according to the Radio Resource pattern configured, select During multiple subscriber equipmenies that communications status is different in same wireless resource communicate, it it is not each subscriber equipment Can receive the upstream data that other subscriber equipment sends, the only subscriber equipment between different grouping is only possible at same wireless It is respectively provided with different communications status in resource, so can reduce in current full-duplex wireless communication systems, due to each use Family equipment all can receive the upstream data of other subscriber equipment, and the interference between the subscriber equipment caused;If base station exists When subscriber equipment is grouped, by disturbing less subscriber equipment to assign to different packets, so can further reduce At present interference between subscriber equipment in full-duplex wireless communication systems.
In other specific embodiment, when performing above-mentioned steps 102, can there be following several situations base station:
(1) when Radio Resource is time-domain resource:
When time-domain resource is measured by subframe (subframe), Radio Resource pattern can be the use of subframe Pattern (is called for short subframe pattern), i.e. specifies which subframe is used as sub-frame of uplink, and which subframe is used as descending sub frame, and which subframe is used Making idle subframe, which subframe is used as flexible sub-frame.Now, base station configures identical subframe pattern to the UE of same packet, gives The subframe pattern differently configured for UE of different grouping.
Wherein, for supporting the system of TDD, subframe pattern can be, but not limited in existing LTE TDDRelease-8 system 7 kinds of ascending-descending subframes configuration (UL-DL subframe allocation) of definition, such as, subscriber equipment in packet 1 is given in base station Configuration ascending-descending subframes configuration 0, gives user device configuration ascending-descending subframes configuration 2 in packet 2;For subscriber equipment between packet Disturbing stronger scene, base station can give that different packet configuration is diverse uses subframe, such as: base station configuration packet In 1, subscriber equipment only uses odd numbered sub-frames, and in configuration packet 2, subscriber equipment only uses even subframe.
(2) when Radio Resource is frequency domain resource:
When frequency domain resource is measured by Resource Block (Resource block, RB), Radio Resource pattern can be frequency The use pattern (being called for short RB pattern) of territory RB, i.e. specifies which RB is used as up RB, which RB and is used as descending RB, which RB Idle RB, which RB are used as flexible RB.Now, base station configures identical RB pattern, to different grouping to the UE of same packet RB pattern differently configured for UE.
For the scene that the interference of subscriber equipment between packet is stronger, base station can be complete to the user device configuration of different grouping The most different used RB, such as: in base station configuration packet 1, subscriber equipment only uses the first half RB in system bandwidth, joins Put subscriber equipment in packet 2 and only use the latter half RB in system bandwidth.
(3) when Radio Resource is time-frequency domain resources:
The use pattern of time-frequency domain resources is i.e. which RB and subframe are used as ascending resource, which RB and subframe and are used as descending Resource, which RB and subframe are used as idling-resource, which RB and subframe and are used as flexible resource.Now, same packet is given in base station The time-frequency domain resources pattern that UE configuration is identical, to time-frequency domain resources pattern differently configured for the UE of different grouping.
(4) Radio Resource is code domain resource, such as N kind orthogonal code or the resource etc. of low associated code, and same packet is given in base station The UE identical code domain pattern of configuration, to code domain pattern differently configured for the UE of different grouping.Such as, in base station configuration packet 1 Subscriber equipment uses orthogonal code 1, and in configuration packet 2, subscriber equipment uses orthogonal code 2 etc..
(5) Radio Resource is spatial domain resource, such as aerial Beam resources etc., and base station configures identical to the UE of same packet Spatial pattern, to the spatial pattern that the UE of different grouping is differently configured, such as, in base station configuration packet 1, subscriber equipment uses sky Middle wave beam 1 to n, in configuration packet 2, subscriber equipment uses and controls wave beam n+1 to m.
With reference to shown in Fig. 2, in another specific embodiment, for the subscriber equipment being grouped according to each more accurately Practical situation reduce interference, base station is performing also to perform before above-mentioned steps 103 step 104 to 106:
Step 104, for each user device configuration reference signal being grouped (Reference Signal, RS) resource, i.e. Specifying which Radio Resource is used as subscriber equipment and sends RS, specifically, base station is that the user device configuration of same packet is identical Reference signal resource, for the reference signal resource that the user device configuration of different grouping is different, wherein this RS is for measuring such as Measure the parameters such as interference strength.
Step 105, is sent to the indication signaling of the reference signal resource of the user device configuration that base station is the second packet The subscriber equipment of the first selected packet, the first packet and second here is grouped and is not offered as ordering relation, and illustrates that Different packets.
In the present embodiment, the instruction of the reference signal resource of the user device configuration for each packet can be believed by base station Order is sent to the subscriber equipment of arbitrary packet, and the subscriber equipment of the such as first packet, so for the subscriber equipment of the first packet For, the RS resource of other subscriber equipmenies being grouped can be known according to indication signaling, and be grouped (such as second point at other Group) subscriber equipment RS resource on, receive the RS that subscriber equipment of other packet sends, the RS's that can be received by measurement Parameter information information such as () such as intensity learns disturbed condition between the subscriber equipment of this packet and the subscriber equipment of other packet, And measurement result is reported base station.
Such as, when the RS resource that second is grouped is sent to the subscriber equipment of the first packet by base station, such first packet Subscriber equipment just in the RS resource of the second packet, can receive the reference signal that the subscriber equipment of the second packet sends, and right This reference signal measures, and measurement result can be reported base station.
Step 106, base station receives what above-mentioned first grouping user equipment sent, the ginseng sending the second grouping user equipment Examining the measurement result of signal, this measurement result is the interference information of subscriber equipment between instruction the first packet and second are grouped, The measurement result such as reported can be the parameter informations such as the intensity of the reference signal received, if the intensity of this reference signal is more Big then interference of between subscriber equipment is the biggest.
After execution of step 106, when performing step 103, not only need the Radio Resource pattern according to configuration, also Need to carry out up-downgoing pairing according to the measurement result received and the subscriber equipment with up-downgoing pairing carries out the nothing of full duplex Line communicates, and i.e. selects to be respectively at different communication state in same wireless resource, and interference each other is less than preset model The subscriber equipment enclosed communicates.Such as, if base station receive measurement result be a certain grouping user equipment report other The intensity of the reference signal that grouping user equipment sends, then be less than pre-by this grouping user equipment with the reference signal strength of transmission Other grouping user equipment of the value put carries out up-downgoing pairing, and less subscriber equipment will be disturbed to match.
Preferably, above-mentioned RS resource can be channel state information reference signals (Channel State Information Reference Signal, CSI RS) resource.CSI RS is used to measure doing between subscriber equipment Disturbing, the UE for the UE of legacy version with backwards compatibility, i.e. legacy version is receiving the CSI that a certain packet UE sends After RS, it is possible to use existing protocol measure interference and report, will this CSI RS be considered as other community send information enter Row is measured.
It should be noted that there is no the ordering relation determined between above-mentioned steps 102 and step 104, can carry out simultaneously, Can also sequentially carry out, the wherein specific embodiment shown in Fig. 2.
In other specific embodiment, base station is except performing above-mentioned steps 101 to 106, in addition it is also necessary to for each point The user device configuration system information (System information, SI) of group, in order to allow subscriber equipment knows access is Parameter information in system, specifically, for the system information that the user device configuration of same packet is identical, for the user of different grouping The system information that equipment configuration section is different.Wherein SI is the call parameter that wireless communication system runs, and can include a master Chunk (Master InformationBlock, MIB) and multiple different types of system information block (System Information Blocks, SIB).SIB includes polytype, and system includes SIB1, SIB2 such as at present ..., SIB13 Deng.
During the SI that base station configures, some SI of configuration is identical such as system bandwidth, and some SI are different, therefore base Standing the SI to the UE configuration of different grouping can part difference.Such as, the user device configuration difference of different packets is given in base station SIB1, specifically, the partial information unit (Information element, IE) in SIB1 may be configured to difference, example As for indicating ascending-descending subframes configuration and the tdd-Config of special subframe pattern, it is used for indicating the si-of SI scheduling window length WindowLength and for indicating the systemInfo ValueTag etc. that system information changes;Different grouping can be given in base station The different SIB2 of user device configuration, such as, physical uplink control channel (the Physical Uplink in SIB2 Control Channel, PUCCH) configuration information etc..
When base station is after being configured with SI, can SI be notified to subscriber equipment, specifically can be come by following several ways Notice:
(1) by the Radio Network Temporary Identifier (Radio Network Temporary Identifier, RNTI) of SI The physical layer descending of i.e. SI-RNTI scrambling controls channel (Physical Downlink Control channel, PDCCH) and holds The signaling carried, by schedule information or the baseline packet (Baseline of system information public in the system information of described configuration The schedule information of system information Group) notifies to subscriber equipment.It addition, base station can change the SI to each packet configuration, And the schedule information updating instruction information of the SI that public SI or baseline be grouped by paging RNTI (Paging RNTI, P-RNTI) signaling to subscriber equipment of the PDCCH carrying scrambled.Above-mentioned schedule information includes that time-frequency domain resources distributes information Such as position and number etc., it is also possible to include modulation coding mode (Modulation and Coding Scheme, MCS) information Deng.
Wherein, public SI refers to be allocated to SI identical in the SI of all packets;Baseline packet refers to that base station is from all In packet, a selected packet is grouped as baseline;SI-RNTI scrambling PDCCH carrying signaling refer to by SI-RNTI with The new signal that the signaling of PDCCH carrying obtains through certain computing such as XOR;The PDCCH carrying of P-RNTI scrambling Signaling refers to the new signal signaling that P-RNTI Yu PDCCH carries obtained through certain computing such as XOR.And this The value of the SI-RNTI described in embodiment is FFFF (16 systems represent), and the value of P-RNTI is FFFE (16 systems represent).
(2) the physical layer descending control scrambled by different group Radio Network Temporary Identifiers (Group RNTI, G-RNTI) The signaling of channel bearing processed, notifies the schedule information of the system information of each packet in the system information of configuration to use to corresponding Family equipment.
Base station is when the schedule information of the SI each being grouped notifies to each subscriber equipment, for the UE of same packet Can use identical G-RNTI, the UE for different grouping uses different G-RNTI, it is preferable that base station can be by special RRC signaling notifies the G-RNTI that each UE is used respectively.Wherein G-RNTI may be used for producing the channel that each packet is corresponding And signal.It should be noted that in the embodiment of the present invention, the RNTI of mark difference group is called G-RNTI, but is also not necessarily limited to this Title.
(3) signaling of the PDCCH carrying that base station is scrambled by SI-RNTI the schedule information of the SI of all packets is notified to Subscriber equipment, such subscriber equipment receives the signaling of the PDCCH carrying of SI-RNTI scrambling, it is possible to according to this schedule information Obtain the SI of the subscriber equipment of all packets, can preferably carry out interference coordination.
